The present disclosure provides a device and a method with which flat glasses with particularly uniform thickness can be obtained. The methods are drawing methods in which a glass ribbon is drawn. In the method an aperture is used which allows a defined very small slit between the glass ribbon and the aperture also in the case of a change of the position of the glass ribbon.

A method for producing ceramizable green glass components provided, as well as apparatus for performing such method and ceramizable green glass components producible by such method. The method is a redrawing process in which a preform is heated, in a deformation zone, to a temperature that enables redrawing of the glass. The deformation zone is particularly small, which permits redrawing of the ceramizable green glass bodies while avoiding ceramization during the redrawing. The method provides plate-like or sheet-like green glass components that have a particularly smooth surface.

The invention relates to glass powder, especially a biologically active glass powder, which includes a plurality of glass particles and which is characterized by the following features: the glass particles are made up by &#x3e;90% of non-spherical particles; the geometry of the individual non-spherical particle is characterized by a ratio of length to diameter of 1.1 to 10.

A process for shaping a body with elongate structures on its surface, bodies produced using the process, and to apparatuses having these bodies are provided. For this purpose, a preform is provided, at the surface, with structures which are elongate along one direction, the preform is heated at least in one region and the preform is drawn in the heated state until at least part of the preform has adopted a cross section which substantially corresponds to the desired cross-sectional shape or final cross-sectional shape. The preform is heated by means of radiation which has a spectral distribution which is such that at most half of the radiation power is absorbed during a single pass through the material.
